Timmy and AHE told me that I had better do the hum pot or the 100 ohm rx's to ground trick on the amp or I would get hum no matter what. OK. I have some 100Ω@ 3W resistors. please take a look at the relevant part of the circuit attached and show me where these center tap rx's should go. I would lift the ground off of "B" and connect a 100 ohm rx to each side with both of other ends of them grounded to chassis ground or taken back to B minus where the filter string starts?
which side of the fil chokes get the rx's, the side going to the tubes; or the side going to the transformers?
I honestly have no idea.
